Apple has released MacBook Pro Software Update 1.0, which "provides important bug fixes and is recommended for all 2.2/2.4GHz MacBook Pro models."

While Apple does not elaborate on the contents of the update, an analysis of the update package indicates that it contains improvements to the graphics subsystem, with updated nVidia graphics drivers and some updated OpenGL components.

Some initial benchmarks of the updated MacBook Pros had indicated some graphics scores lower than its predecesor. This had been speculated to be caused by faulty graphics drivers. This update would seem to be an attempt at correcting these issues.
